We design, build, and ship the compliance, verification, and automation engines that regulated platforms run on — from zero to production. A small, senior team obsessed with craft, correctness, and outcomes.
Solyd Services is an Estonian RegTech company building compliance and verification infrastructure for regulated platforms. Founded in 2025 in Tallinn, we operate with a senior team of engineers and cryptographers — partnering with operators in crypto, gaming, and fintech who can't afford the bolt-on compliance stack.
We care deeply about code quality, mathematical correctness, and shipping things that actually work in production — not just in demos. Small team, high standards, zero bureaucracy.
These are Solyd's product investments — engines we own, build, and deploy in production for partners in regulated markets.
Compliance Automation Engine
One engine for fraud detection, withdrawal routing, AML enforcement, audit trails, and operator command. Built for platforms that can't afford the bolt-on compliance stack — every alert, every escalation, every report in one system, with deterministic rules and a single dashboard.
Cryptographic Verification Engine
HMAC-based verifiable computation for platforms that need to prove fairness, randomness, and result integrity to users and regulators alike. Every output mathematically verifiable end-to-end — no trust required, no after-the-fact disputes.
Supporting Infrastructure
Beyond Sentinel and Verify, we operate the supporting infrastructure regulated platforms need:
Multi-currency precision wallet
Type-safe accounting across crypto and fiat, designed to make USD+BTC bugs impossible at compile time.
Multi-PSP payment orchestration
Intelligent failover routing across crypto and fiat rails — no single point of failure in your payment stack.
Alongside our products, we offer custom development engagements for selected partners building in regulated industries — architecture reviews, compliance integrations, and bespoke RegTech tooling. We take ownership of the entire build: architecture, implementation, testing, and deployment. No hand-holding required.
End-to-end product builds from concept to launch. We take ambiguous briefs and turn them into shipped software with real users.
Scalable backends, RESTful and GraphQL APIs, real-time data pipelines, and the service architecture to support them.
High-performance web apps and interfaces. React, Next.js, and modern tooling — with a relentless focus on UX detail.
Infrastructure-as-code, CI/CD pipelines, container orchestration, monitoring, and cost optimisation across AWS, GCP, and Azure.
Third-party API integrations, internal tooling, data connectors, and automation workflows that save teams hundreds of hours.
Codebase audits, architecture reviews, and migration planning for companies that need a second pair of senior eyes.
We start with a deep-dive into your product, constraints, and goals — aligning on scope, tech stack, and success metrics before a single line is written.
We design the system before building it. Data models, API contracts, infrastructure diagrams — the unsexy work that makes everything else easier.
Iterative development with real feedback loops. Weekly demos, async updates, and continuous deployment so you see progress, not promises.
Clean documentation, tested codebases, and a knowledge transfer that leaves your team empowered — not dependent on us.
